  • Battery State of Health (SOH)
  • Battery Status
  • Individual Cell Voltage
  • Battery Temperature
  • Battery Cycles
  • Battery Alarms
  • Battery Event Information

Advanced Battery Management

Inside the Enerdrive B-TEC 12V 100Ah Slimline lies an intelligent Battery Management System (BMS) that continually monitors and optimizes each Prismatic cell. It safeguards against overcharging, over discharging, overheating, and short circuits, ensuring the safe and precise operation of the battery.

Note that a fully discharged battery (BMS is off) should be recharged within 14 days to prevent cell damage.

Typical Size and Weight Comparison

Experience a remarkable power-to-weight ratio with the Enerdrive B-TEC 12V 100Ah Slimline. Compare its Lithium vs. AGM capacities, and you’ll see the advantage:

  • 100Ah Lithium = 160Ah AGM
  • 125Ah Lithium = 200Ah AGM
  • 200Ah Lithium = 320Ah AGM
  • 300Ah Lithium = 480Ah AGM (Based on standard depth of discharge for both Lithium (80%) and AGM (50%).

This Enerdrive B-TEC lithium battery provides 60% more usable power than its lead acid counterpart while being nearly 50% lighter and 30% smaller, making it an exceptional choice.

Versatile Applications: The Enerdrive B-TEC 12V 100Ah Slimline battery is ideal for various applications, including camper trailers, 4WDs (AUX battery), caravans, small watercraft, low-power communication sites, and any setup requiring a single deep cycle battery that meets amp hour capacity requirements.

Important Notes:

  • The B-TEC Slimline battery can be paralleled with another of the same size, but a maximum of 2 batteries should be connected to avoid exceeding current limits.
  • The 100Ah Slimline battery can handle a maximum inverter capacity of 1000W. Exceeding this limit may damage the battery’s BMS Management.
  • For larger battery systems, explore Enerdrive Pro Series Power Pack Systems, which offer multiple parallel and series connections with Active Cell Balancing Protection.
  • Ensure proper battery placement by avoiding vehicle engine bays, high-heat environments, wet areas, or compartments for carrying gas. This electronic product is designed for internal use only.

Stay Informed About Standards: Stay ahead of the curve with the 2023 Standards Update. To address any confusion regarding upcoming standards changes and their impact on battery fitments for future and existing builds, ENERDRIVE | DOMETIC has created a comprehensive fitment guide.

This guide, specific to e-LITE and B-TEC battery ranges, covers all aspects of battery installation requirements under the new standard. Please note that this guide is tailored to Enerdrive batteries and does not apply to other manufacturers.
